Addicted to teen TV shows

I have always considered myself a pretty well grounded woman but I have begun to wonder if I don't have some kind of inner issue that needs to be dealt with. I love tv shows that are generally geared towards teens like Pretty Little Liar, Mom at 16, and Glee. I find myself secretly watching them and and then I surf the internet to look for discussions about them. I once mentioned to one of my friends about Pretty Little Liar and she looked at me like I had horns in my head and asked me why on earth I would be watching a show for teens. Please tell me I am not the only adult that watches these kind of shows.
